Abstract
A piezoelectric resonator includes a base member in which piezoelectric layers and internal electrodes are laminated. At one side surface of the base member, the internal electrodes are alternately covered with a first insulating film and with a second film, and first and second external electrodes are disposed thereon alternately connecting the internal electrodes to the first and second external electrodes. An additional material is disposed on the side surface of the base member opposite from the side surface on which the external electrodes are formed by applying ink via an ink jet printer or the like. The additional material is disposed at the opposite ends of the base member in the longitudinal direction. A metal film may also be disposed at a central portion of the base member by a thick film forming method.
